I also tried this: https://forums.alliedmods.net/showpo...&postcount=240
but it's not working either: [11] <FAILED> file "PTaH.ext.so": /(...)/left4dead2/addons/sourcemod/extensions/PTaH.ext.so: cannot open shared object file: No such file or directory
Because you need to use the PTaH extension, which isn't available for L4D2.
